Fix path for search index items

Browse Source 
rustdoc clears the path of an item in the search index if it is equal to
the path of the previous item (see build_index in html/render.rs).
Previously, we used the crate name if the path was empty.  With this
patch, we use the past of the last item instead.

//! Note that the format of the search index changed in April 2020 with commit

//! For details on the generation of the search index, see the `html/render/cache.rs` file in
